  • We have fabricated polymer light-emitting diodes(PLED) in a structure of Glass/ITO/PVK/Al. Poly(N-vinylcabazole) (PVK) was deposited on the ITO glass with the spin coating method. PVK thickness is respectively 500nm, 300nm, 250nm and 200nm with the spin coter rotation speed of 2000, 3000, 4000 and 5000rpm. V-I, wavelength-transmittance, P-L and SEM of the fabricated devices were measured. From the result of P-L measurement, it was kept the optic properties of PVK raw powder when PVK thickness is 250nm. The knee-voltage of PVK PLED with 250nm thickness was 7V.
